The air gradually turns cool, people begin to add clothes to keep warm, to prevent a cold. Similarly, the car is also changing with the season of such a failure.
After the summer sun and rain, at the junction of the car battery is likely to appear oxidation failure. Battery is the car on the main storage device, to provide power for the vehicle electronics system, and its importance is beyond doubt, the modernization of increasingly high degree of automotive electronics, stronger and its dependence on the car battery, the battery power shortage will lead to paralysis of the vehicle. Therefore, the car battery maintenance and maintenance becomes very important.
Two kinds of batteries
Battery used in general for the use of lead-acid batteries. There are two types of common lead acid batteries, one of which is water - type lead acid storage battery, the other is maintenance free lead-acid battery. Currently on the market more than 80% of the models used in the battery is free maintenance lead acid battery.
Water - type lead acid battery: the plate of the ordinary battery is made of lead and lead oxide, and the electrolyte is the water solution of sulfuric acid. Its main advantage is the voltage stability, the price is cheap; the disadvantage is that it is lower (that is, per kilogram of battery stored electric energy), short service life and frequent maintenance.
Maintenance free lead-acid battery: maintenance free battery due to the advantages of its structure, the consumption of the electrolyte is very small, in the use of life is not essential to add distilled water. It also has the characteristics of high temperature resistance, shock resistance, small volume, small self discharge. The service life is two times of common battery. Market maintenance free battery has two kinds: first at the time of purchase disposable add electrolyte after use does not need to maintain (adding and supplementing the liquid); another is a battery factory has increased the electrolyte and sealed, users simply can't add supplementary liquid. |
